Abstract: A tethering system is provided for a washing machine having a hung strut suspension. The tethering system includes a pair of pulleys or cams pivotally mounted in the cabinet. A pair of subframe straps are secured between the cams and the subframe of the hung assembly. An anti-rotation strap extends partially around the tub with opposite ends secured to the cams.      When the tub of the machine is filled with water, the hung assembly moves downwardly due to the weight of the water, thereby rotating the cams which tighten the anti-rotation strap into frictional engagement with the tub. Thus rotation and oscillation of the tub is prevented during the agitation and low speed spin cycles of the machine.

Abstract: Screen (10) for a user interface of a television schedule system and process consists of an array (24) of irregular cells (26), which vary in length, corresponding to different television program lengths of one half hour to one-and-one half hours or more. Because of the widely varying length of the cells (26), if a conventional cursor used to select a cell location were to simply step from one cell to another, the result would be abrupt changes in the screen (10). By restricting cursor movements to the regular cells, abrupt screen changes will be avoided. A conventional offset shadow (34) which is a black bar underlines the entire cell and wraps around the right edge of the cell. To tag the underlying position which defines where the cursor (32) is and thus, where it will move next portions (36) of the black bar outside the current underlying position are segmented, while the current position is painted solid.

Title: Fingerprint identification device equipped with a touch sensor for detecting a human finger
Inventor: KASAI EIJI
IPC: G07C9/00
Filed: 1999-11-29
Granted: 2004-08-03
Abstract: A fingerprint identification device judges that the input fingerprint is identical to the fingerprint in the database only when a the touch sensor detects the human finger and a the fingerprint processing unit detects that the input fingerprint is identical to a fingerprint in the database. The touch sensor includes an oscillator that outputs a high frequency signal. An electrode unit applies the high frequency signal to the human finger. A detector unit detects a variation of impedance values varied by the human finger contracting the electrode unit and outputs an output signal based on the variation of impedance values. A discriminator unit determines whether the human finger is in contact with the electrode unit by comparing the output signal from the detector unit with a predetermined reference value.

Abstract: A method and apparatus for I/O forwarding in a cache coherent shared disk computer system is provided. According to the method, a requesting node transmits a request for requested data to a managing node. The managing node receives the read request from the requesting node and grants a lock on the requested data. The managing node then forwards data that identifies the requested data to a disk controller. The disk controller receives the data that identifies the requested data from the managing node and reads a data item, based on the data that identifies the requested data, from a shared disk. After reading the data item from the shared disk, the disk controller transmits the data item to the requesting node. In one embodiment, an I/O  destination handle is generated that identifies a read request and a buffer cache address to which the data item should be copied. The I/O destination handle is transmitted to the disk controller to facilitate transmission and processing of the data item from the disk controller to the requesting node. As a result of forwarding data that identifies the requested data directly from the managing node to the disk controller ("I/O  forwarding"), the duration of a stall is reduced, contention on resources of the system is reduced and a context switch is eliminated.

Title: Cellular stirrups and ties for structural members
Inventor: KONSTANTINIDIS APOSTOLOS
IPC: E04C5/18
Filed: 1998-11-04
Granted: 2007-05-08
Abstract: The present invention refers to stirrups and ties for structural members. Such stirrups and ties are used in all the structural members like columns, beams, slabs, footings, piles, chainages, lintels etc. The invention refers also to a method of reinforcement of structural members and to the structural members themselves. According to the invention the stirrup or tie consists of a load-bearing element (20) for the fixing of the longitudinal rebars (10) and for the undertaking of the tensile forces which develop during the loading of the structural member. The bearing element consists of at least one cell of closed shape (50) so that the flow of the tensile stresses developed in the cross section is closed and the stresses are not diffused to the concrete. The load-bearing element of the stirrup or tie in accordance to the invention has a continuous cross section and thus there are no free ends as in the known stirrups. In this way anchoring of the stirrups or ties is completely avoided. The closed cellular shape has no discontinuation and may be simple, i.e. rectangular, circular, T-shaped, I-shaped, etc. or complex i.e. square with inscribed rectangular, circular with inscribed square etc.

Abstract: A vehicular transmission comprises an engine E, a continuously variable transmission CVT and a starting clutch 5. The driving force from the engine E is conveyed through the continuously variable transmission CVT with a speed change to a countershaft 2, and the starting clutch 5 is used to convey this driving force from the countershaft 2 to wheels of a vehicle. The continuously variable transmission CVT is hydraulically controlled by a control valve CV which receives control signals through a line 35 from an electrical control unit ECU. When the temperature of the oil used for engaging and disengaging the starting clutch 5 is equal to or higher than a predetermined temperature, the transmission allows the engine E to stop operating. This control to terminate the operation of the engine is an idling elimination control and is achieved by terminating the fuel supply to the engine and by maintaining the resulting condition of non-fuel supply while the vehicle is being decelerated and brought into a halt.
